Another preferred means can be AA still further Object of my invention 'is to proprovided for connecting the intake tube 19`with vde an improved charge forming device for inthe cap 12, and, as shown, I have provided nuts termal Combustion engines, which will be ex- 20 for this purposei The lower end of the tube 10.5

tremely durable and efficient in use, one thatY 19 is preferably cutoff at an angle as indicated Y will be simple and easy to manufacture and one by the reference Acharacter 21 to facilitate the which can be placed upon thev market and incorentrance of the crank case gases into the same porated with an engine at a small cost; and the tube is provided with a plurality of inlet With these and other objects in view, the in-v openings 22. These inlet openings 22 are in vention consists in the novel constructiomarrelative Close proximityto one another and the 110 exact number thereof can be determined by experimentation according to the size and the type of the engine with which my device is associated.

` Leading from the tube 19 is a conduit pipe 23 which is of a relatively large diameter, so that the ho-t gases collected by the tube 19 from the crank case will readily iiow through the conduit pipe. Supported in an elevated position are a pair of `jars o-r receptacles 24 and 25'. These jars can be arranged in any desired position, but I prefer toy mount the same on the dash board 19 of a motor vehicle by the use of suitable clips or the like.

The jar 24 is of a larger size than the ljar 25 and receives a light lubricating oil 26. This oil is placed in the jar 24 until the same substantially half fills the jar. The upper end of the jar is closed by a cap 27 and this cap supports the depending delivery tube 28.

The tube 28 extends into the oil and terminatesv short of the lower end ofthe jar. The lower Yend of the tube28 can be angled as at 29 and the portion of the tube, which is immersed in the oil can be provided with outlet openings 30. I prefer to provide a less number of the openings 30 than the openings 22in the tube 19, as I have found that more advantageous resultsdcan behad by utilizing a comparatively small .number of openings in the outlet tube 28. Y

The conduit pipe 23 is connected/.to the tube 28, such as by the use of a nipple 31 and thus the vapors taken from the crank case will be introduced directly into the oil 26. The cap 2.7 also supports an outlet nipple 32 at one side of the tube 28 and this nipple 32 has connected therewith, a short conduit pipe 33 Which leads into the jar 25 throughk the 4vuse of `a suitable nipple 34. The nipple34 is carried by the cap 35 of the jar 25. As shown, the conduit pipe Y33 Yis of arelatively small diameter and of a less diameter than the conduit pipe 23. A second nipple 36 is connected Awith lthe cap 35 ofthe jar 25 and this nipple' receives 'the Ysuction pipe 18, heretofore referred to.

v'rhejar 25 is one-hair'niid .withanigmy veiatile liquid, such as high test gasoline 37 or alcohol. In operation of my improved device, the vvsame is connected With the internal `combustion engine as described, and when the engine is Arunning, a constant suction 1'will be-created in theY suction pipe 18, as is readily understood by those skilled in the art. The suction `,in the pipe 18 will in turn create a suction inthe jar 25 and this suctio-n will in turn create a suction inthe jar 24 through the conduit'33. The suction in the jar 24 will create ra suction in a vpipe 23 Which'will in turn suck the ho-t vapors "from the crank case 6 into the intake tube 19. ,Y

Thus, the hot vapors sucked from the crank case Will .ow through the pipe 23 and will be introduced intothe oil `26 in the jar 24. The

' passage of thesevapors through the oil Will tend to purify these vapors and at the same time permit the vapors'to-be charged with the o il. lThese vaporsin turn flow through the pipe 33 andas this pipe is of a relatively .small diameter, the vapors Vare impinged Vwith considerable force ing the Y lower ends.

against the surface of the volatile uid 37 in the jar 25. The vapors then pick up the gaseous vapors in the jar 25 and these charged vapors then flow into the intake manifold directly in advance of the carburetor. This charge mingles with the charge leaving the carburetor and is introduced into the cylinders of the engine therewith.

I have found by actual experiments `that my charge thus formed gives many advantages to the engine over the usual carbureted charge, and the same will reduce to a large extent, the formcarbon in the engine. The oil picked up by crank case vapors from the jar 25 Will be deposited on the valves and thus insure Vthe 90 proper lubrication thereof at all times and thus prevent the sticking of said valves. My device operates without noise of any kind and my device aiso tends to relieve objectionable noises generally apparent during the running of an engine.

InV Figure 3 of the drawing, I have illustrated a preferred means supporting the yjars Yon a dashboard of a vehicle, and this means maycomprise a head 40 for'fned from a singlercasting. This casting preferably includes depending caps 41 and 42 integrally connectedjtogether .by a bridge piece 43.

These caps 41 and 42 are internally threaded for receiving the necks of the jars containing the light lubricating oil and gasoline respectively. The bridge piece 43 can` support in any desired way a reinforcing bar 44 having yokes 45 and 45 for engaging the jars and adjacent .to their The caps 41 and 42 have formed thereon the nipplesY 'l and 48 for receiving the suction and intake pipes respectively, While the bridge piece 43 is provided with a port 49 for forrninfr communication between the jars.

Attaching ears 49 can be formed on the casing to facilitate the securing of the casting on the dashboard of the vehicle. Y

Changes in details maybe made without departing from the spirit of the scope ofwthis invention, but whatv I claim as new is- As a new article of manufacture, an auxiliary charge forming device for internal combustion engine adapted to be associated with ordinary engines and a fuel supply system therefor,.com prising a pairof independent jars, said jars being partially lled respectively with oil and a volatile liquid, an intake manifoldgasket, an intake suction pipe communicating with the gasket, means connecting the suction pipe with the upper end of the jar containing the volatile liquid, a crank case vapor collecting tube, a discharge tube extending into the oil in the other jar and terminating short of the lower end thereof, La conduit of relatively large diameter connecting the vapor collectingV tube and discharge tube vtogether,v and a conduit of relatively small diameter connecting the upper end of the jar containing the oil with the upper end of the jar'containing the volatile liquid, whereby the cleansed oil laden air will be impinged on the upper surface of the 1'40 volatile liquid.
